Step 1. Read the documentation on select-options and how their data is structured

Step 2. Define appropriate types either in an interface, or in the data dictionary (if FM is to be RFC)

Step 3. Create a function module (and function group if not using an existing one) frdric.girod

Step 4. Create parameters with the type of the select-options you need as defined in Step 2.

Step 2, courtesy of sandra.rossi , many thanks.

matthew.billingham It's worth an answer, and I think you miss the creation of the type between Step 2 and 3, I would recommend defining the type in an interface (or DDIC if it's a RFC function module).

and we don't know if there is a function group ..

(but Why they still using FM ?!?)

Have a look at the "good example" under

https://help.sap.com/doc/abapdocu_latest_index_htm/latest/en-US/index.htm?file=abenencap_class_interf_guidl.htm

The example uses PARAMETERS, but of course, the same holds for SELECT-OPTIONS.

But why are all the methods static?

Because it is generally sufficient for dealing wit classical dynpros in local classes of function pools. You can do it with singletons if you like but I don't see a benefit of multiple objects dealing with one program-global dynpro.

I know, we have https://help.sap.com/doc/abapdocu_latest_index_htm/latest/en-US/index.htm?file=abenstatic_class_singleton_guidl.htm, but simply encapsulating classical dynpros runs under exceptions for me.
